Having worked for a number of large organizations, let me try to give some insight into how these companies work today.
The first that it is usually less expensive to buy something if it is available outside. Think, for example, of Garner Holt Productions. If you have in-house production capacity for animatronics, it is hard to ramp up or ramp down. With an outside vendor you can buy as much as you need, when you need it. The same thing is happening with entertainment, and I believe that is a good thing.
Unfortunately, an old company like Disney ends up with layer upon layer of expensive management, and that is a bad thing. Think of all the pictures you see of 20 Disney managers standing around watching something, when in reality you need only 1 or 2. So the next step in the process is to lean-out the management chain. Not sure if this is happening yet, but eventually it will. Costs will drive it that way (managers are expensive).
The third is to extract as much money from the buyer as you can, and you all know about MM+.
